Structure for reducing power dynamic shock response on back of seamless bridge table

The utility model discloses a structure for reducing the power dynamic shock response on the back of a seamless bridge table. A butt strap is embedded into filled earth on the back of the table and is integrally connected with a back wall. A backfill layer is arranged on the upper portion of the embedded butt strap to scatter part of the shock load and lower the shock action exerted on the butt strap. Cover earth in the length range of the embedded butt strap and an earth body at the tail end of the butt strap are used for forming a common thick and long elastic body to absorb the telescopic deformation of a beam body. According to the structure, the upper vehicle load is easily scattered, the direct action of a vehicle on the butt strap is relieved, the butt strap is prevented from being broken, part of the upper cover loads are borne through the butt strap, the additional stress on a lower earth base is reduced, post-construction settlement of the earth base is reduced, excessively large road and bridge differential settlement is avoided, sudden change of settlement of a seamless bridge transition section is changed into slow change of settlement, and bump at a bridge head is avoided. The shock resistance performance of a seamless bridge is improved, and the structure is particularly suitable for integral bridge table seamless bridges.
